Answer:
x = 8
Step-by-step explanation:
Hello!
What we do to one side of the equation we have to do to the other side.
3x - 6 = 18
Add 6 to both sides
3x = 24
Divide both sides by 3
x = 8
The answer is 8
Hope this helps!

Answer:
i < 3u
Step-by-step explanation:
9x-7i> 3(3x-7u)
to solve for i, first simplify the problem on the right side of the equation.
9x-7i > 9x - 21u
make i the subject by subtracting 9x from both sides of the equation
9x-9x-7i> 9x-9x -21u
add like terms
-7i > -21u
divide both sides of the equation by -7
-7i/-7> -21u/-7
divide and change the sign
i < 3u
